After the making three films, all comedies, actor/writer/director Alex Karpovsky (best known for his smarmy turn as Lena Dunham's love interest in "Tiny Furniture") is heading to Tribeca with "Rubberneck," his first foray into the thriller genre. The film premieres on April 20 at the festival, and we've got the exclusive trailer.

In a First Person he wrote for Indiewire, Karpovsky described the film as "a slow-burning, character-driven psychosexual thriller revolving around a scientific laboratory on the outskirts of Boston."
